Where can I buy double knobs to radio stack and gauges rings for cessna 152?

Hello
I'm building home-made cessna 152 cockpit.
I have two bigs problems. I can't find in Poland in any electric shops double knobs to my radio stack. I was looking for everywhere. Where can i buy it? (I hope it's not very expensive)

Second problem is a gauges rings for cessna. I drilled holes in wooden panel and i must to install black rings on this panel. I'm asking the same question: Where can i buy it?

Thanks for help!
